The purpose of present study is to obtain the fundamental data of urethane grout for forepoling as one of the auxiliary method. Especially, the foaming pressure and penetration mechanism of urethane grout was discussed in the model or actual ground with various permeability coefficients. The aboratory test on solidified shape, which had two parameters (penetration range & foaming pressure), was carried out. From the test result, it was ascertainedt hat the permeability coefficient of ground significantly influenced the penetration mechanism and solidified shape of urethane grout.
